    I just ordered a new iMac and I'll be upgrading from a 1GHz TiBook with Tiger on it. I have some important music software that I'm not 100% sure will work with Snow Leopard, but my understanding is that it's already ok for Universal Binary...so I had the thought that maybe I could put Tiger on the iMac and dual boot. Can I do that? I've never dealt with a dual-boot system before, other than a couple times when I played around with Classic Mode when I still had Jaguar and/or Panther.

    Most probably not, as Macs coming with Mac OS X 10.6.2 can have any Mac OS X version below 10.6.2 installed, so no 10.6.1 or 10.5 or even 10.4.

    It also would create havoc, as Tiger has no drivers for your hardware in it, and Apple doesn't release 10.4.x drivers for machines that came with 10.6.2.

    But maybe there is a workaround.

    You can have different OSes on different drives. For example an external HD.

    You MIGHT be able to do it on even internal partitions as well. I haven't tried that one though, but I don't see why it wouldn't work.

    10.5.8 is possible but even it has some issues with running on the new 21.5" iMacs.

    Nope.

    Retail Tiger disks are for PPC machines.
    Intel Tiger disks are machine specific and definitely none were made for the 21.5" imac.

    What music software are you using? Maybe someone here is also using it, and can tell you if it works on Snow Leopard.

    You can try it, but I would expect a kernal panic within seconds of starting up from a Tiger disc.

    What he said.

    Even trying a Leopard Retail Disc wouldn't work as those new iMacs never shipped with Leopard therefore the discs don't have the proper drivers.

    I personally wish that Apple would allow virtualization of Tiger/Leopard on OS X itself. I wouldn't mind booting into Tiger every now and then for nostalgic reasons; haha, I'm sure there are practical reasons though.

    that wont work.
    Even if you had the retail version of tiger.

    You computer came out with snow leopard,snow leopard has the drivers for the new iMac.

    Tiger has no drivers for your iMac,it won't work.

    If you iMac came out with 10.4,then yeah you can dual boot the machine with 10.6

    Digital Performer 5, Logic Express 7, Reason 3.0, and Finale 2007. I have a thread on that topic in the Digital Audio section, but haven't gotten any actual answers yet.

    What Consultant said.

    Somehow I missed that this is the new iMac. I thought the system already had Tiger and you wanted to upgrade the OS but keep a working copy of the old one on it.

    :eek:

    D'oh.

    There is a work around, you could modify the OSInstall file, and install Tiger on any machine..

    Duff-Man says...I would try reading (or posting) in the forums at MacOSX Audio - they have sections for most apps and get a bit more traffic for specialty audio apps than you might get here (and maybe already have answers for each of those apps).....oh yeah!
